I have found that womanless pageants are common in small towns in the southern USA. They are usually associated with Spirit Week in high schools, and also Rely For Life and other charities regularly hold them. If you are looking to volunteer you might find opportunities in Facebook. I don't know anything about this one, but I just Googled "womanless pageant Facebook" and found it: http://www.operahousetheatrecompany.net/
